Well if Mazda copied the 944 then maybe Porsche copied the 240Z?

Or was it Ferrari's Daytona? Or better yet.. the Opel!

Seriously I always wondered if Porsche seen something there with the success of the Z. If I remember right the 240Z was spanking 911s. Maybe Porsche seen potential in the design? I don't know, but it seemed sorta obvious to me.
